Note: Waterproof roofing sealant Sealant should be used on roofs for waterproof purposes. Consult with local roofing company for further details. 6

7 SECTION 4 PLANNING YOUR INSTALLATION ON ROOF 4.1 Installation Zone Confirming the installation zone is the first step. Center the installation zone over the roof structural members as much as possible. Panels should provide a gap between 50mm and 300mm between the underside of the panel and the roof surface. Use the following table (TABLE 4.1) to find out the minimum distance between panel and roof edge (A) in Fig.4.1 according to the roof height. TABLE 4.1 MINIMUM DISTANCE BETWEEN PANEL AND ROOF EDGE (A) ROOF SHORT EDGE DISTANCE OF ROOF (m) HEIGHT (m) Source from: AS/NZ The width (W) of the installation zone equals the length of whole module. The length (L) of the installation zone will equal to the following; the total width of the modules, plus 26mm for each space between modules (for mid-clamp) and plus 80mm (Minimum 40mm for each panel away from edge of rail). See FIG Please leave enough room to safely move around during installation. FIGURE 4.1 INSTALLATION ZONE 7

8 4.2 Design Considerations Wind After deciding the installation zone, define the wind region where the property is located. The Australian Standards AS is to be considered, regarding the following: The regional design wind speeds; The terrain category of a building site; Local requirements and covenants determined by State and/or local statutory authorities. The installation specifications given in this manual are based on a wind speed for ultimate strength of 69m/s (ultimate serviceability wind speed in Region D) at a height under 15m from ground level (see Report on Adequacy of Bracketry to Support Solar Panels on Rooves For MicroSolar System) and is designed to support for installations using Aluminium Solar PV Module Mounting System manufactured by MSS. This is suitable for sites in Australian Regions A, B and New Zealand. For installation specifications for designated cyclonic areas i.e. Region C and D it is also advisable to refer this manual or to consult your local building engineer Wind Force The pressure that wind created must be considered when specifying roof structures and roofing materials. In most situations, when wind comes across roofs, negative pressure (lifting force) will exert on a roof and the negative pressure will be much greater than the weight of a PV panel (FIG ). Therefore determining the wind force affecting the site at certain height is essential to identify the appropriate level of security installation. Figure LIFTING FORCE ON ROOF Source from: AS/NZ Basic Wind Speed AS /Amdt 3 and AS 4055 provide information on wind speeds generally affecting different regions of Australia and New Zealand (FIG and TABLE 4.2.2).Wind regions are pre-defined for all of Australia and New Zealand by AS SAA Loading Code Wind Loads. The wind region has nothing to do with surrounding topography or buildings. 8

10 TABLE THE SERVICEABILITY REGIONAL WIND SPEEDS Regions Vp (m/s) A 41 B 49 C 57 D 69 Source from: Report on Adequacy of Bracketry to Support Solar Panels on Rooves for MicroSolar System Pty Ltd. * Note. All the Region A(1 7) are defined as Region A All the areas in New Zealand are defined as Region A This manual provides sufficient information for PV module mounting system being installed on any roof less than 15 meters of height. Please call MSS for assistance if required. 4.3 Rail Spacing Under normal circumstances, each module requires two rails for support. The ideal spacing between the rails is 50% ~ 70% of one module length, but no greater than 80% of its length. This rule applies to all types of roofs. For accurate installation, please refer to the roof structure.(under special cases, please contact MicroSolar System Pty Ltd for further information). 4.4 Footing Types and Spacing for Different Roof Types Different types of roofs require different footing structures and spacing Roof Types - Tile roof - Tin roof -Non-penetration needed KLIP-LOK 406/ 700 -Penetration needed All other tin-roofs (e.g. Flat Roofs, Corrugated Roofs) 10

11 4.4.2 Footing Types There are four types of footings for installation on tile roof Tile Hook (MSTSS), Side Tile Hook (MSTSS-S), Vertical Tile Hook (MSTSS-V) and Horizontal Tile Hook (MSTSS-H); depending on the roof structure situations, different footing types are used. Tile Hook (MSTSS) Side Tile Hook (MSTSS-S) Vertical Tile Hook (MSTSS-V) Horizontal Tile Hook (MSTSS-H) KLIP-LOK Clamp (MSCL) is used for non-penetration needed tin roofs KLIP-LOK 406 (MSCL-406) and KLIP-LOK 700 (MSCL-700).

13 *Note: The tables show above is based on attaching a pair of rails to panels with 808mm x 1600mm and 20Kg in size and weight; also to panels with size and weight no greater than 1100mmx1800mm, and 30kg each. Otherwise, please consult with MSS. These tables are suitable for the roofs with any angles and directions. All the footing spacing is calculated with the greatest wind pressure either in Upwind Zone, Central Zone or Downwind Zone. All the footing spacing shall be used for Terrain Category 3 or below. Rail overhang must be equal or less than 40% of the foot spacing required. Rails should not extend more than 390mm from the edge of Panels. 13

14 SECTION 5 INSTALLING PV MODULE Follow the recommended step by step instructions for installing PV Module. 5.1 Step One: Joining Rails with Splices If length required, two or three rails can be joined together as one continuous rail with Splicer(s). Keep rail slots clear from debris and roof grit. External matter will cause bolts to bind as the slide into the slots. Place the Splicer into the right position, 1-1.5mm gap should be left between the rails to allow thermal expansion; and bolt it to the rail slots with the T-Bolts M8x25 with flange nuts provided (FIG. 5.1) Attach the rails together by using Splices before mounting the rails to the footings. Try to avoid using more than two splices within one continuous rail line. Structure wise, the Splicer joiner is not as strong as the rail itself. Please note that each rail should always be supported by more than one footing on either sides of the splicer. FIGURE 5.1 Join two rails together using Please contact MSS when experiencing special cases or concerning about thermal expansion issues. 5.2 Step Two: Attach Rails to Roof Structure In accordance to the roof types, use one of the methods bellow for attaching Tile Roof There are four types of stainless steel Tile Hook which are suitable for most common types of tile roof in Australia and New Zealand.
